I've heard if you switch inputs to another then back to the HDMI then it starts going 5.1.

Thanks for the suggestion tcat but no go.

Just to clarify... from the Xbox, hdmi goes to the TV and also from the Xbox, optical goes to Receiver.

Reading the S/PDIF specs on Wikipedia I see that...
"S/PDIF is based on the AES3 interconnect standard.[1] S/PDIF can carry two channels of uncompressed PCM audio or compressed 5.1/7.1 surround sound (such as DTS audio codec); it cannot support lossless formats (such as Dolby TrueHD and DTS-HD Master Audio) that require greater bandwidth..."

So I tried with a DVD that gave the option to choose DTS 5.1 but this didn't work either, Receiver still showing PCM 2.0 as input.

Does anyone know if the receiver is capable of decoding 5.1 via its optical input or maybe it's the xBox optical output that's not supporting 5.1.

The source device must be set to "bitstream" in order to pass DD/DTS 5.1 to the AVR which an indeed decode it.
